摘要:
浮选是回收细粒锡石的有效方法，其中捕收剂的选择对选矿指标有较大的影响。羟肟酸属于螯合类捕收剂，在浮选过程中能够与锡石形成四元或五元环的螯合物实现对锡石的捕收，具有良好的捕收性与选择性。本文综述了羟肟酸类捕收剂的特点及其在锡石浮选中的应用实践，探讨了金属离子活化和药剂协同作用在锡石浮选中的影响，为羟肟酸类捕收剂的研制及其在锡石浮选中的推广应用提供参考。
Abstract:Recovery of fine cassiterite mineral from ores by flotation has been proved an effective process in mineral processing. The collectors determine the quality of the beneficiation index. Hydroxamic acid is a chelating collector of cassiterite with high performance in the flotation process, which form four or five-membered ring chelate with cassiterite. In this paper, the characteristics of hydroxamic acid collectors and their application in cassiterite flotation were reviewed. The effects of metal ion activation and synergistic action of reagents on cassiterite flotation were discussed.
